ACR 3764 HemiLight 3 Automatic Survivor Locator Light, Yellow

Great light to add to your PFD. Battery replacement is not possible so be sure to check and keep track of the expiration date on the light. Activation is very quick when exposed to water. The button is only used to deactivate the light. Only way to test the light is to place in water.

Haven’t had to use it yet, thankfully, but it seems to work when I put water on the sensor. Looks to be bright enough for if you fall in the ocean and need a light.

This is the same size and function as the Dan Buoy Man Overboard Marker strobe. The Marker is in a vinyl bag which keeps water off of the strobe contacts, but we did as suggested by another reviewer and placed a piece of cloth medical tape over the contacts to reduce the chance of unwanted activation from light moisture, while allowing emersion to soak through the tape and activate the strobe.

Watch for expiration date! Came with over a year already off the total battery replacement period. Otherwise, product is good quality and works as intended.

Simple. Click on a belt or strap of life jacket or harness, pants, etc. Extremely lightweight . Will not notice it’s there. Simply too cheap to not buy for night time activity on the water. Makes the MOB man overboard immediately visible and able to be recovered. Save someone's life for $10 or less.

I use two of these on my inflatable PFD, one in front and one behind my neck. They're bright and self-activating. I also have one attached to my ditch bag. Easy, small, and bright strobes. Worth it!

Just sailed the Port Huron to Mackinac Race and need a new emergency light for my PDF. this light is great, small, very bright and attached to my PDF perfectly.

Excellent product and water resistance

Great device, works well. I'm on a marine search & rescue crew and this is my choice for beacon. Non replaceable battery lasts about 2 years or less depending on use. I do put a small piece of fabric hockey tape over the water sensor. This protects against the strobe turning on accidentally when splashed, but if immersed, soaks through and activates.

Item received with button dented. Not sure how this will affect the functionality of the product.

Conforme aux descriptions de l'article. J'ai testé la lampe avec de l'eau et ça marche ! Luminosité assez forte à éclats. Par contre, énorme boite pour si petit article; pas très écolo l'emballage !!!!

Lumière puissante comme décrit livraison rapide

Very very sensitive to water. Much more sensitive than my older unit that it replaced. At least I can cancel it.
